I don't remember other games with this engine crashing so often but maybe they were using a different version
RPG Maker MV is heavily prone to system crashs based on "out of RAM" errors.
Several factors play in hand here.
For starters the game is based on a x86 (32-Bit) engine, which already reduces the possible RAM the game can manage.
3rd party Scrpits (like the raiding mechanic or the lightning effects) tax the RAM additionally.
Some games also have memory leaks makeing the game allocate more and more RAM, while never clearing the old one (PQ thankfully doesn't seem to have that problem)
And finally Animations are requiring quiet some RAM
The smaller the game and the less custom content it holds the less is the chance for crashes
